The Rusty-flanked Treecreeper, also known as the Nepal Treecreeper, is a small, elusive bird belonging to the family Certhiidae. Its plumage is an intricate pattern of browns and whites, providing excellent camouflage against the tree bark it so often frequents.
This species can be identified by its slender, down-curved bill, perfect for probing into crevices in search of insects. Its upperparts are mottled with brown and white, while the defining rusty flanks give this bird its common name.
The Rusty-flanked Treecreeper is at home in both boreal and temperate forests, where it can be seen deftly navigating the trunks and branches of trees.
This bird graces the northern regions of India, the mountainous landscapes of Nepal and Bhutan, and extends its range into western Yunnan.
True to its name, the Rusty-flanked Treecreeper exhibits a creeping behavior as it ascends tree trunks in a spiral fashion, meticulously searching for insects hidden within the bark.
The IUCN Red List categorizes the Rusty-flanked Treecreeper as Least Concern, indicating that, for now, this species does not face immediate threats to its survival.
